Description

The present invention relates to a luminaire.
The present invention is suitable for battery-powered luminaires and emergency luminaires.
The present invention is suitable for a lighting fixture such as an emergency lighting fixture that is embedded and fixedly arranged in a mounted portion such as a ceiling.

An emergency luminaire characterized by thermally coupling an LED substrate and a power supply substrate has been presented (see, for example, Patent Document 1).
However, in the configuration described in Patent Document 1, since the LED substrate and the power supply substrate are thermally coupled, when one of them is driven, it is not intended for the other non-driven substrate. There was a problem of giving heat.

Further, an emergency lighting fixture is presented in which two thermally separated spaces are provided in the main body of the fixture and a light source and a lighting circuit are housed in each space (see, for example, Patent Document 2).
However, in the configuration described in Patent Document 2, since the light source and the circuit board are housed in one of the storage spaces, there is a problem that heat is applied to the circuit board when the light source is turned on.

Further, an emergency lighting fixture is presented in which the heat generated by the LED is efficiently radiated and irradiated for a predetermined time by contacting the heat radiating portion provided with a plurality of heat radiating fins with the light source portion provided with the LED (for example). , Patent Document 3).
However, Patent Document 3 does not describe heat dissipation from the heat radiating portion of the emergency lighting fixture to the outside of the fixture. When the heat radiating portion dissipates heat to the inside of the fixture, it is considered that the ambient temperature of the LED rises, and the luminous flux of the LED is attenuated and the life of the LED is shortened.

In addition, an emergency lighting fixture has been presented that makes it possible to reduce the size of the fixture body by projecting a lighting device to the side of the fixture body, to reduce the diameter of the fixture installation hole, and to reduce the size of the design part (for example). , Patent Document 3).
However, in the emergency lighting fixture described in Patent Document 3, the lighting device protruding to the outside of the fixture main body increases the space occupied by the fixture after installation, and it is necessary to consider adjacent construction materials and other fixtures. Will be done.

Further, an emergency lighting fixture in which a battery is inserted through a battery insertion opening and the battery is attached to a battery mounting portion is presented (see, for example, Patent Document 4).
However, Patent Document 4 does not describe the device of the guide used when inserting the battery of the emergency lighting equipment. If the guide is not devised, the connector connection may not fit properly, and there is a problem in the detachability of the battery.

In addition, an LED lighting device that serves as the main light source is placed outside the fixture, and an inspection switch and monitor LED are provided separately from the LED substrate that serves as the main light source, and an emergency lighting fixture that is placed next to the LED that serves as the main light source. Is presented (see, for example, Patent Document 3).
However, in the configuration described in Patent Document 3, since the LED substrate and the monitor LED are provided on the same substrate, the monitor LED is unintentionally affected by the heat of the LED of the main light source. Further, since the LED as the main light source and the monitor LED are arranged on the same substrate, there is a problem that the arrangement of the monitor LED cannot be easily changed even when the arrangement is desired to be changed.

Further, an emergency lighting fixture in which an LED for a monitor is mounted on the same substrate as an LED as a main light source and an inspection switch is used as a separate substrate has been proposed (see, for example, Patent Document 5).
In the configuration described in Patent Document 5, since the monitor LED and the inspection switch are provided separately from the substrate on which the LED as the main light source is arranged, there is a degree of freedom in arrangement, but the lighting device is arranged outside the fixture. Therefore, there is a problem that the installation work of the equipment is restricted.

Further, a battery storage box in which a connector is attached to a connector holding portion of a battery case has been proposed (see, for example, Patent Document 6).
In the configuration described in Patent Document 6, it is necessary to attach the lid to the connector holding portion of the battery case after attaching the connector. In addition, the connector could be attached only from the outside of the battery case.

Further, there has been proposed a lighting device in which a confirmation hole is formed in the bottom plate of the sheet metal so that the insulating plate and the heat dissipation pad can be confirmed from the outside through the confirmation hole (see, for example, Patent Document 7).
In the configuration described in Patent Document 7, since the case body of the lighting device is made of metal, it is necessary to arrange an insulating sheet inside. If the insulating sheet is transparent, the internal heat dissipation pad can be confirmed from the confirmation hole, but if the insulating sheet is a colored material, it cannot be seen.

Further, an LED lighting fixture is presented, which is characterized by adding a heat sink to the heat radiating portion to improve the heat radiating effect. (See, for example, Patent Document 8.)
In the configuration described in Patent Document 8, mold costs are incurred when manufacturing a heat sink, and in the case of an appliance in which the heat sink is arranged in the main body, air convection is small even if the heat sink is added. Therefore, there is a concern that the heat dissipation effect is small.

Further, a lighting fixture in which a pair of cover mounting springs is attached to the fixture body is presented (see, for example, Patent Document 9).
In the configuration described in Patent Document 9, the cover mounting spring is hidden by the cover at the time of mounting, and there is a problem that the cover mounting spring cannot be mounted well at the time of mounting. In addition, there is no means for positioning the cover mounting spring, and there is a possibility that the cover mounting spring may be inserted in a completely different place.

In the event of a power outage due to a fire or the like, emergency lighting equipment has its structure and installation standards stipulated by the Building Standards Act so that a certain level of illuminance can be secured and evacuation can be carried out promptly.

An emergency lighting fixture that lights up in the event of a power outage in the event of a fire or the like must ensure a predetermined brightness (floor illuminance 1 lpx at high temperatures) even in an emergency such as a fire.

In recent years, LEDs that have become widespread as a light source have their luminous flux attenuated as the temperature rises. Therefore, it is an important issue to dissipate heat from the LED.

In addition, a dedicated type emergency lighting fixture equipped with only an emergency light source has a presence as a lighting fixture because the battery is charged and the light source is not lit during regular use other than during a power outage. Smaller ones are preferable, and there is a demand for reduction of equipment installation space and power saving.

In the embodiment of the present invention, it is desired to efficiently dissipate the heat generated from the light source of the lighting equipment.

Further, in the embodiment of the present invention, it is desired to improve the assembling property of the lighting equipment.

Further, in the embodiment of the present invention, it is desired to reduce the size and improve the reliability of the lighting equipment.

Further, in the embodiment of the present invention, it is desired to improve the mountability of the battery unit in a small space of the lighting equipment.

Further, in the embodiment of the present invention, it is desired to provide an inspection unit that can be used in different lighting fixtures.

Further, in the embodiment of the present invention, it is desired that the connector can be easily fixed from the inside of the case of the lighting device. Furthermore, we would like to make it possible to easily attach the connector even in a miniaturized case of the lighting device.

Further, in the embodiment of the present invention, it is desired to make the internal parts of the lighting device visible while ensuring the insulation of the internal parts of the lighting device.

Further, in the embodiment of the present invention, it is desired to efficiently dissipate the heat generated from the light source by standardizing the parts and reducing the cost as much as possible.

In the embodiment of the present invention, it is desired that the cover mounting spring can be inserted at the correct position at the time of mounting.

The luminaire 100 includes a main body 10, a light source unit 20, a lighting device 30, a battery unit 40, a power terminal block 50, and an inspection unit 60.
The lighting device 30, the battery unit 40, and the power terminal block 50 are internal parts housed in the lighting fixture 100.
The main body 10 has a tubular shape.
The main body 10 is made of a non-combustible material such as metal.
The main body 10 is attached to the ceiling by the fixture mounting portion 102. As the instrument mounting portion 102, the instrument mounting bracket 14 is suitable.
The light source unit 20 has a light source 26 and is attached so as to close the opening of the main body 10.
The lighting device 30 is arranged inside the main body 10 and supplies electric power to the light source 26.
The lighting device 30 functions as a control device for lighting the light source 26.
The battery unit 40 is arranged inside the main body 10, stores a storage battery, and supplies electric power to the lighting device 30.
The power terminal block 50 is arranged at the back of the main body 10 and connects an electric wire from an external commercial power source to supply electric power to the lighting device 30.
The inspection unit 60 inspects the lighting of the lighting fixture 100.

The main body 10 will be described with reference to FIG.
The main body 10 has a bottomed cylindrical shape having an opening 101 on one surface.
The main body 10 is a metal housing that houses the lighting device 30, the battery unit 40, and the power terminal block 50.
One of the main body 10 is opened by the opening 101, and the opening 101 is covered by the light source unit 20.

The main body 10 has a back plate 11, a side plate 12, a collar 13, and an instrument mounting bracket 14.
The back plate 11 is a metal circular plate that closes the back direction of the main body 10.
The side plate 12 is a metal cylindrical plate having a pipe shape.
The brim 13 is formed in the shape of an eave at the end of the opening 101 of the side plate 12, and has a donut shape.
The diameter of the collar 13 is larger than the diameter of the fixture insertion hole in the ceiling, and the collar 13 is attached to the edge of the fixture insertion hole in the ceiling. The lighting fixture 100 is fixed to the ceiling by sandwiching the ceiling plate from above and below between the collar 13 and the fixture mounting bracket 14.

The back plate 11 has a screw hole 111, a screw hole 112, and a terminal exposed hole 113.
The screw hole 111 is a hole through which the screw 19 for fixing the power terminal block 50 penetrates.
The screw holes 111 may be arranged only on the side plate 12 of the main body 10 or on the back plate 11 and the side plate 12 to fix the lighting device 30.
The screw hole 112 is a hole for fixing the screw 18 for fixing the lighting device 30.
The terminal exposure hole 113 is an opening for exposing the power supply terminal block 50.
The wire 114 is a wire that is fixed to the main body 10 or the back plate 11 of the main body 10 and connects the light source unit 20. When the wire 114 is fixed to the main body 10 instead of the back plate 11 of the main body 10, the fixing position of the wire 114 may be near the opening 101 of the side plate 12 of the main body 10.
The lighting device 30 and the light source 26 built in the main body 10 are electrically connected by the light source harness 336, but prevent tension from being applied to the light source harness 336 when the light source unit 20 is attached to and detached from the main body 10. Therefore, a wire 114 shorter than the light source harness 336 is attached to the frame 29 and the main body 10. As the wire 114, a string, a metal wire, or the like is used to serve as a tension prevention wire.

The side plate 12 has a battery fixing metal fitting 121, a horizontal stopper 122, a slit 123, and a light source mounting hole 124 shown in the cross-sectional view taken along the line BB in FIG.
The battery fixing bracket 121 is a V-shaped leaf spring, and is fixed to the inner peripheral surface of the side plate 12 in a state of being opened in a V-shape in the back direction. The battery unit 40 is fixed at the opening end opened in a V shape to prevent the battery unit 40 from falling in the opening direction.
The horizontal stopper piece 122 is a rectangular piece obtained by cutting a part of the side plate 12 into a rectangular shape in the lateral direction to form a screw hole and bending it inside the main body 10. The horizontal stopper piece 122 is used for screwing the lighting device 30 from the lateral direction.

The slit 123 is a linear opening formed in the vertical direction of the side plate 12.
Two slits 123 are formed so as to be elongated in the vertical direction of the side plate 12 and opposed to each other in the diametrical direction, and the instrument mounting bracket 14 is attached to each of the slits 123.
The instrument mounting bracket 14 is mounted in the work space arrangement direction X.
The fixture mounting bracket 14 is a bracket for mounting the lighting fixture 100 to the ceiling.
The instrument mounting bracket 14 is slidably mounted in the vertical direction with respect to the slit 123.
The fixture mounting bracket 14 slides the slit 123 vertically to the back surface of the ceiling to fix the lighting fixture 100 to the ceiling.
The light source mounting hole 124 is a rectangular opening formed in the opening direction of the side plate 12.
Two light source mounting holes 124 are formed so as to face each other in the diameter direction of the side plate 12, and the frame mounting bracket 25 of the light source unit 20 is mounted in the longitudinal direction Y of the lighting device.
The work space arrangement direction X and the lighting device longitudinal direction Y are orthogonal to each other.

As shown in the DD opening view of FIG. 2, the lighting device 30 has an oval shape when viewed from the vertical direction.
The long side L of the lighting device 30 is the same as the inner peripheral diameter of the main body 10.
Since the short side S of the lighting device 30 is shorter than the long side L, a pair of fixture mounting work spaces 70 are formed on both sides.
In the DD opening view of FIG. 2, the lighting device 30 has a dent space 74 for accommodating the battery unit 40 in the central portion of the right side surface, and the portion having the dent space 74 is shorter than the short side S. The width is W.
Therefore, on the right side of the lighting device 30, an appliance mounting work space 70 wider than the fixture mounting work space 70 on the left side is formed.
In the DD opening view of FIG. 2, the space length K1 in the radial direction of the fixture mounting work space 70 on the left side of the lighting device 30, the width W of the lighting device 30, and the diameter of the fixture mounting work space 70 on the right side of the lighting device 30. The ratio of the direction to the space length K2 is 2: 4: 4.
The reason why the instrument mounting work space 70 on the right side is wide is that it is used as a battery mounting space 71 for accommodating the battery unit 40.

As shown in the cross-sectional view taken along the line BB of FIG. 2, the light source unit 20 is attached via the heat blocking space 72 when viewed from the lateral direction.
In the cross-sectional view taken along the line BB of FIG. 2, the vertical length K3 of the heat blocking space 72 is 17% of the height T of the main body 10 of the luminaire 100, and is preferably 10% or more and 20% or less.

The outer shell of the lighting device 30 is made of a resin.
The lighting device 30 has a storage space 73 for accommodating the power supply terminal block 50 in the back direction, facing the back plate 11. The storage space 73 is a recess recessed in the opening direction from the surface of the lighting device 30 in contact with the back plate 11.

As shown in the BB sectional view of FIG. 2, the battery unit 40 is arranged in the battery mounting space 71 inside the main body 10 and supplies electric power to the light source 26.
The battery unit 40 is detachably mounted in the battery mounting space 71.
The battery mounting space 71 occupies a part of one fixture mounting work space 70 of the pair of fixture mounting work spaces 70.

The power terminal block 50 is fixed to the back plate 11 and exists in the back center of the main body 10.
One side of the power terminal block 50 is exposed from the terminal exposure hole 113, and an electric wire from an external power source is connected from the terminal exposure hole 113.
The power terminal block 50 has a terminal body 51 and a terminal mounting plate 52.
The terminal mounting plate 52 is a cover for fixing the terminal body 51 to the back plate 11 with screws 19.
The power terminal block 50 is housed in the storage space 73 of the lighting device 30 and does not project outward from the side surface 353 of the lighting device 30.

*** Explanation of the structure and assembly of the lighting fixture 100 ***
The main body 10 is attached to the ceiling by using the fixture mounting bracket 14.
The fixture mounting bracket 14 is fitted in a slit 123 provided in the main body 10, and the main body 10 is fixed to the ceiling by installing the fixture on the ceiling and sliding the fixture mounting bracket 14 downward.
As a method of fixing the main body 10 to the ceiling, a method using a leaf spring may be used.

The lighting device 30 has a rectangular parallelepiped shape having a long side L, a short side S, and a height H.
The lighting device 30 is arranged so that the height H is in the vertical direction, and the long side L and the short side S can be seen from the opening 101.
The lighting device 30 is arranged across the center of the main body 10 when viewed from the opening 101.
The lighting device 30 is fixed so that the longitudinal direction of the lighting device 30 crosses the work space arrangement direction X.
That is, the work space arrangement direction X and the long side L of the lighting device 30 are orthogonal to each other, and the longitudinal direction Y of the lighting device 30 and the short side S of the lighting device 30 are orthogonal to each other.
A pair of fixture mounting work spaces 70 are formed between the side surface 353 having the long side L of the lighting device 30 and the inner peripheral surface of the main body 10. It is desirable to increase the instrument mounting work space 70 by setting the long side L >> short side S.
Since there is a pair of fixture mounting work spaces 70 in the work space arrangement direction X, the vertical movement of the fixture mounting bracket 14 that slides the slit 123 in the vertical direction is not hindered.
The outer peripheral surface 354 having the short side S is a curved surface having the same radius R as the inner peripheral surface of the main body 10, and the outer peripheral surface 354 is inscribed in the inner peripheral surface of the main body 10.
The lighting device 30 has a screw fixing portion 37 protruding from the side surface 353 at the back of the side surface 353.

The assembly method and the mounting method of the luminaire 100 will be described with reference to FIG.
S1. The terminal body 51 is attached to the terminal mounting plate 52.
S2. The terminal body 51 and the lighting device 30 are connected by a terminal block harness 54. Further, one end of the light source harness 336 is connected to the lighting device 30.
S3. The terminal mounting plate 52 is attached to the lighting device 30. At this point, the power terminal block 50 is stored in the storage space 73 of the lighting device 30.
S4. The lighting device 30 is inserted in the depth direction from the opening 101, and the lighting device 30 is housed in the main body 10. At this point, the power terminal block 50 is housed in the main body 10 together with the lighting device 30 while being housed in the storage space 73 of the lighting device 30.
S5. The screw 19 is screwed from the screw hole 111 into the screw hole 53 to fasten the power terminal block 50 to the back plate 11. The power terminal block 50 exposes one surface of the terminal body 51 from the terminal exposure hole 113 and is fixed to the center of the back plate 11 of the main body 10.
Further, the horizontal stopper piece 122 of the main body 10 and the screw boss 325 of the lighting device 30 are fastened with the screw 191. Further, the screw 18 is screwed into the screw hole 112 of the back plate 11 of the main body 10 to fix the screw fixing portion 37 of the lighting device 30 to the main body 10.
The lighting device 30 is fixed to the main body 10 so that the long side L is in the longitudinal direction Y of the lighting device and the short side S is in the work space arrangement direction X.
The screw fixing portion 37 of the lighting device 30 is fixed to the back plate 11 with a screw 18 from the inside of the main body 10, but since the screw fixing portion 37 exists in the back of the fixture mounting work space 70, the screw 18 is screwed in. The work is easy.
At this point, the instrument mounting work space 70 is formed between the side surface 353 and the inner peripheral surface of the main body 10 in the work space arrangement direction X.
S6. An instrument mounting bracket 14 (not shown in FIG. 3) is attached to the slit 123 of the main body 10. Since the instrument mounting work space 70 exists around the slit 123 inside the main body 10, the instrument mounting bracket 14 can be easily mounted.

*** Explanation of the structure and assembly of the light source unit 20 ***
The light source 26 is mounted in a recess in the center of the surface of the socket 24.
The socket 24 has a structure in which the light source 26 is sandwiched between the light source 26 and the lens 21, and power is supplied to the light source 26 by a connection terminal built in the socket 24.
A connector 243 is attached to the tip of the electric wire 242 connected to the power supply terminal of the socket 24. The connector 243 is fixed to the connector fixing hole 272 of the light source mounting portion 27 to prevent tension from being applied to the power supply terminal of the socket 24.

The socket 24 is made of a material such as ceramics or resin.
Since the heat generated from the light source 26 is conducted to the light source mounting portion 27 via the socket 24, the material of the socket 24 is preferably a material having high thermal conductivity.
Further, a heat radiating sheet or grease for reducing the contact thermal resistance may be applied between the light source mounting portion 27 and the socket 24.

The lens 21 is arranged on the light emitting surface side of the socket 24.
In order to fix the positions of the lens 21 and the socket 24, the socket 24 and the lens 21 are provided with positioning mechanisms at positions facing each other.
Specifically, as shown in FIG. 8, the lens 21 is provided with a recessed recess 211 on the surface in contact with the socket 24, and the socket 24 has a protrusion-shaped protrusion at a position corresponding to the recess of the lens 21. A portion 241 is provided.
In FIG. 8, the concave portion 211 of the lens 21 and the convex portion 241 of the socket 24 are provided at three places, but the quantity may be appropriately changed according to the shape. The lens 21 may be provided with a convex portion and the socket 24 may be provided with a concave portion.

The lens 21 has a shape corresponding to a desired light distribution, and in the present embodiment, the lens 21 has a hemispherical or dome-shaped lens 21 protruding from the frame 29. The shape of the lens 21 may be appropriately changed according to the light distribution.
Further, the lens 21 does not have to protrude from the frame 29.
The lens 21 is preferably made of non-combustible glass, but may be made of a transparent resin such as polycarbonate or acrylic, silicon, or the like.
When used as an emergency lighting fixture, the outer shell of the fixture needs to be a non-combustible material. Therefore, when the lens 21 is made of a material other than glass, it is necessary to cover the outer shell of the lens 21 with a glass cover.

The lens 21 in the present embodiment has a hemispherical or dome-shaped protrusion from the lens hole 295 of the frame 29, and light is emitted from the protruding lens surface. At that time, if the inspection switch 62 protrudes from the frame 29, the emitted light may hit the inspection switch 62 and a desired light distribution may not be obtained.
The emergency lighting fixtures mounted on a low ceiling with a height of 2 to 3 m have a light distribution with a peak of luminous intensity at a shallow angle (60 °), so the light is lit by the frame 29 and the pull rod type inspection switch 62. May be blocked.
Therefore, it is necessary to arrange the lens 21 and the inspection switch 62 in consideration of the direction (angle) emitted from the lens 21.
In the present embodiment, the lens 21 is projected in a hemispherical or dome shape so that the emitted light does not hit the inspection switch 62.
Further, a convex protrusion 291 is provided around the lens hole 295 of the frame 29, and the lens 21 is arranged in the light emitting direction. In this way, the positions of the lens 21 and the inspection switch 62 in the vertical direction are shifted so that the light distribution is not affected.

The lens 21 has a hemispherical or dome-shaped shape, and a brim portion 212 is provided on the outer peripheral portion of the lens 21. A ring-shaped packing 22 is attached to the brim 212, and when it comes into contact with another member, it is possible to prevent the lens 21 from being damaged by an impact. The packing 22 is made of, for example, silicon.

The frame mounting bracket 25 has a function of fixing the frame 29 and the light source mounting portion 27 and a function of fixing the light source unit 20 and the main body 10.

The light source unit 20 is fixed to the main body 10 by using the mounting plate portion 253 of the frame mounting bracket 25.
The shape of the mounting plate portion 253 of the frame mounting bracket 25 is such that the width becomes narrower toward the tip in accordance with the shape of the main body 10. As shown in FIG. 10, W1> W2.
Fixing the main body 10 and the frame 29 requires a holding force of a certain level or more. Therefore, a certain width is required when holding the frame mounting bracket 25 by utilizing its elasticity. On the other hand, since the main body 10 has a tubular shape and a circular cross section, and the cross-sectional shape of the frame mounting bracket 25 is straight, when the mounting plate portion 253 has a certain width or more, both ends of the mounting plate portion 253 become the main body. It interferes with the light source mounting hole 124 of 10.
Further, since the main body 10 has a cylindrical shape, if the width of the mounting plate portion 253 of the frame mounting bracket 25 is large, the spring must be flexed by that much for mounting.
Therefore, in order to maintain the holding force and not interfere with the main body 10, the mounting plate portion 253 at the tip of the frame mounting bracket 25 is adjusted to the shape of the main body 10 and the width is narrowed toward the tip so as not to interfere. It is possible to secure the holding power even in the state.

The light source mounting portion 27 is fixed to the frame 29 by the fixing plate portion 251 of the frame mounting bracket 25.
As shown in FIG. 11, the frame 29 is provided with a bridge 293 for fixing the frame mounting bracket 25, and the light source mounting portion 27 has a bridge insertion hole at a position corresponding to the bridge 293 provided on the frame 29. 273 is provided.
The fixing plate portion 251 that fixes the frame 29 and the light source mounting portion 27 is a three-pronged portion 2511 having a three-pronged shape, and three teeth are formed in the three-pronged portion 2511. The teeth at both ends of the three-pronged portion 2511 are present on both ends sides of the bridge insertion hole 273. The teeth at both ends of the three-pronged portion 2511 have a bent portion 256 bent in a V shape on the side where the light source mounting portion 27 is located rather than the central tooth. Since the bent portion 256 presses the thin portion 275 against the frame 29, it has a function of bringing the frame 29 and the light source mounting portion 27 into close contact with each other.
As shown in FIG. 12, the central tooth of the three-pronged portion 2511 is inserted under the bridge 293. When the insertion of the central tooth of the three-pronged portion 2511 into the bridge 293 is completed, the cut-up 255 is caught on the outer wall of the bridge insertion hole, and the frame mounting bracket 25 cannot be removed. After fixing the light source mounting portion 27 to the frame 29, the cut-up 255 prevents the frame mounting bracket 25 from coming off.

As described above, the frame mounting bracket 25 has a function of bringing the frame 29 and the light source mounting portion 27 into close contact with each other. Further, since the frame mounting bracket 25 brings the frame 29 and the light source mounting portion 27 into close contact with each other, the frame mounting bracket 25 has a function of bringing the lens 21 into close contact with the frame 29 and the socket 24.

Here, a method of assembling the light source unit 20 will be described with reference to the exploded perspective view of FIG.
The socket 24 is fixed to the socket storage portion 271 of the light source mounting portion 27 with screws 23.
Next, the connector 243 is inserted into the connector fixing hole 272 to fix the connector 243 to the light source mounting portion 27.

Next, the packing 22 is put on the brim 212 of the lens 21.
Next, the concave portion 211 of the lens 21 is aligned with the convex portion 241 of the socket 24, and the lens 21 is aligned with the socket 24.
Next, the frame 29 is placed on the lens 21, and the lens 21 is sandwiched between the frame 29 and the socket 24. At this point, the lens 21 is in a state in which the movement in the horizontal direction is restricted by the positioning mechanism between the concave portion 211 and the convex portion 241 provided in the socket 24 and the protruding portion 291 of the frame 29.
When the frame 29 and the light source mounting portion 27 are aligned, as shown in FIG. 12, the bridge insertion hole 273 provided in the thin portion 275 of the light source mounting portion 27 is aligned with the bridge 293 provided in the frame 29. In this state, the bridge 293 of the frame 29 is higher than the thickness of the thin portion 275 of the light source mounting portion 27 by the height I, and the central tooth of the three-pronged portion 2511 of the frame mounting bracket 25 is inserted when viewed from the side surface. It will be ready.

As shown by the arrow in FIG. 12B, the frame mounting bracket 25 is inserted from the radial outside of the frame 29 toward the central axis O, and the central tooth cut-out 255 is inserted into the bridge insertion hole 273. The frame mounting bracket 25 is fixed to the frame 29 in this state.
The frame mounting bracket 25 has a raised 255 on the central tooth, and when the insertion is completed, the raised 255 is caught on the outer wall of the bridge insertion hole 273, so that the frame mounting bracket 25 can be removed even when a force is applied to the outside in the radial direction. Can be prevented.
In this way, the light source mounting portion 27 and the frame 29 are fixed only by the frame mounting bracket 25, and no screws or adhesives are used.
With the above, the light source unit 20 is completed.

The heat dissipation of the light source unit 20 will be described.
Since the light source 26 is fixed to the front surface of the socket 24 and the back surface of the socket 24 is fixed in surface contact with the socket storage portion 271 of the light source mounting portion 27, the heat of the light source 26 is transferred to the socket 24 and the light source is mounted. It is transmitted to the part 27.
The light source mounting portion 27 is fixed to the frame 29 by using the frame mounting bracket 25, and the frame 29 and the light source mounting portion 27 are in close contact with each other, so that the frame 29 and the light source mounting portion 27 are thermally coupled. The light source mounting portion 27 is in surface contact with the back surface of the frame 29 in the 360-degree direction with the light source 26 as the center, and the frame 29 and the light source mounting portion 27 are thermally connected.

On the other hand, as shown in the cross-sectional view taken along the line BB in FIG. 2, the light source unit 20 is arranged with respect to the lighting device 30 and the battery unit 40 via the heat cutoff space 72. Since the heat blocking space 72 exists between the light source mounting portion 27 and the lighting device 30, the light source unit 20 and the lighting device 30 are thermally separated from each other. Further, since the heat blocking space 72 exists between the light source mounting portion 27 and the battery unit 40, the light source unit 20 and the battery unit 40 are thermally separated from each other.

Further, as shown in FIG. 13, the back surface of the light source mounting portion 27 is arranged with respect to the collar 13 via the space S1. The light source mounting portion 27 has an outer peripheral surface 277 along the inner peripheral surface of the main body 10.
The outer peripheral surface 277 of the light source mounting portion 27 is arranged with respect to the inner peripheral surface of the main body 10 via the space S2. As described above, since the space S1 and the space S2 exist between the light source mounting portion 27 and the main body 10, the light source unit 20 and the main body 10 are thermally separated from each other.
In this way, most of the heat radiation to the outside air is performed from the frame 29.

*** Explanation of the effect of the light source unit 20 ***
According to the present embodiment, since the frame 29, the light source mounting portion 27, the socket 24, and the light source 26 are thermally connected, the heat generated from the light source 26 is dissipated through the light source mounting portion 27 and the frame 29. Therefore, the heat of the light source 26 can be efficiently dissipated from the frame 29 to the atmosphere.

According to the present embodiment, the frame 29 is thermally connected to the light source mounting portion 27, and the heat generated from the light source 26 can be dissipated through the frame 29, so that the life of the light source is extended.
According to the present embodiment, since the light source unit 20 is thermally separated from the lighting device 30 and the battery unit 40, which are internal parts of the main body 10, the degree of freedom in layout inside the fixture is improved, and the fixture is made smaller. It becomes possible to realize the conversion.

According to this embodiment, the light source 26 is electrically insulated from the light source mounting portion 27 and the frame 29 by using the socket 24.

According to this embodiment, by fixing the frame 29 and the light source mounting portion 27 with the frame mounting bracket 25, the number of parts such as screws can be reduced and the assembling property can be improved.
Further, since the frame 29 and the light source mounting portion 27 are attached by sliding the frame mounting bracket 25 in the lateral direction, there is no possibility that the frame 29 will fall in the vertical direction.

According to the present embodiment, the mounting plate portion 253 of the frame mounting bracket 25 is tapered so as to follow the curved surface of the main body 10, the amount of deflection can be reduced, the workability is improved, and the spring It is possible to prevent sagging.

According to this embodiment, the lighting fixture 100 can be used as an emergency lighting fixture by using a non-combustible material.

According to the present embodiment, by projecting the lens 21 with respect to the frame 29, it is possible to irradiate the floor surface without blocking the light.

According to the present embodiment, since the light source mounting portion 27 and the frame 29 are only fixed by sandwiching the lens 21 only by sliding the frame mounting bracket 25, the assembling property is improved.
Further, since there is no fixing mechanism for fixing only the lens, the number of parts can be reduced.

According to this embodiment, since there is no misalignment of the lens 21, the light distribution is accurate.

When the illuminance range is different, it is possible to deal with it by changing the output of the light source 26 and the shape of the lens 21.
Further, when the emergency lighting time is different, it is possible to deal with it by changing the capacity of the battery unit 40.

The battery unit 40 of the first embodiment is configured to use five AA cells (AA size), but when the capacity is increased, the battery unit 40 is located inside the main body 10 in the upward or downward direction or in the lateral direction. In addition, an enlarged battery unit 40 can be used, and the battery can be changed to C cell or the number of cells can be increased.

When increasing the capacity of the battery unit 40, it is possible to change the size or number of cells. At that time, it is necessary to change the shape of the battery unit 40, but this can be dealt with by enlarging the outer shell of the case of the battery unit 40 without changing the fitting structure M using the guide rib 46 with the lighting device 30. ..
Regarding the method of changing the shape of the battery unit 40, it is conceivable that the shape of the battery unit 40 is expanded in the height direction of the appliance as shown in FIGS. 19 and 20, and the diameter of the appliance is expanded as shown in FIGS. 21 and 22. ..
When it expands in the height direction of the fixture, it can be dealt with by changing the height of the fixture while keeping the diameter of the fixture the same.

On the other hand, when the diameter of the appliance is increased, it is possible to deal with it by changing only the outer shape of the appliance without changing the height of the appliance.
These are appropriately selected according to the form of the device.

In the fixture embedded in the ceiling shown in FIG. 20, since the fixture height does not affect the design surface, it is desirable to change the fixture height without changing the fixture diameter.
In the battery unit 40 shown in FIG. 19, a part of the battery unit is arranged from the lighting device 30 in the opening direction where the opening 101 is located.
The battery unit 40 shown in FIG. 19 has the same fitting structure M as in the first embodiment, and has an enlarged portion N in the vertical direction.
In the fixture embedded in the ceiling shown in FIG. 20, the enlarged portion N of the battery unit 40 is arranged on the side of the lighting device 30 where the light source unit 20 is located. The enlarged portion N of the battery unit 40 is located between the lighting device 30 and the light source unit 20, and as in the first embodiment, the fixture mounting work space 70 is secured on both sides of the lighting device 30, so that the fixture mounting work space 70 is secured. It does not hinder the movement of the metal fitting 14.
In the fixture embedded in the ceiling shown in FIG. 20, it is difficult to secure 10% or more of the height T of the lighting fixture 100 for the vertical length K3 of the heat blocking space 72, but a gap of 5% or more is provided. It is better to secure and insulate.

The battery unit 40 shown in FIG. 21 has a semi-cylindrical shape, has the same fitting structure M as that of the first embodiment in the center, and has an enlarged portion N in the radial direction. The outer peripheral radius of the battery unit 40 is the same as the inner peripheral radius of the enlarged main body 10.
In the fixture directly attached to the ceiling shown in FIG. 22, if the height of the fixture is changed, the amount of protrusion from the ceiling surface increases. Therefore, it is desirable to increase the diameter of the fixture while keeping the height the same.

In the fixture directly attached to the ceiling shown in FIG. 22, the main body 10 has a pair of fixture mounting holes 115 in the work space arrangement direction X.
The lighting device 30 is fixed to the main body 10 so as to cross the linear direction connecting the pair of fixture mounting holes 115 and not to block the fixture mounting holes 115.
The fixtures that are directly attached to the ceiling are fixed to the ceiling with screws, but by laying out the lighting device 30 in the center of the main body 10, the fixture mounting work space 70 is formed at a position symmetrical to the center of the fixtures. It is possible to expose the instrument mounting hole 115 in the opening direction. The instrument mounting hole 115 is formed in the work space arrangement direction X, similarly to the slit 123 of the first embodiment. That is, by forming the instrument mounting hole 115 in the depth direction of the instrument mounting work space 70 of the back plate 11, a screwing work space to the ceiling can be secured.

In the fixture directly attached to the ceiling shown in FIG. 22, a space is created between the outer peripheral surface 354 of the lighting device 30 and the inner peripheral surface of the main body 10, so that the left and right parts of the enlarged portion N of the battery unit 40 are lit. It is arranged in a space between a part of the outer peripheral surface 354 which is a side surface having a short side of the device 30 and the inner peripheral surface of the main body 10.

Even in the appliance directly attached to the ceiling shown in FIG. 22, it is desirable that the power terminal block 50 is arranged at the center with respect to the main body 10. This is because when drilling a hole in the ceiling, the hole is drilled in the center where the fixture is attached, and the electric wire from the back of the ceiling can be easily attached to the power terminal block 50.

In the fixture directly attached to the ceiling shown in FIG. 22, the main body 10 is integrated with the frame 29 of the light source unit 20, and the main body 10 is exposed in the air.
Therefore, it is desirable to eliminate the spaces S1 and S2 between the light source mounting portion 27 and the main body 10 shown in FIG. 13, bring the light source mounting portion 27 into contact with the main body 10, and transfer heat from the light source mounting portion 27 to the main body 10.
Since the main body 10 is exposed in the air, the heat dissipation effect is enhanced and the temperature of the light source 26 can be lowered.

*** Explanation of effect ***
According to the present embodiment, by sharing the fitting structure M using the guide rib 46 with the lighting device 30 in the battery unit 40, only the battery unit 40 is changed while sharing the common lighting device 30. This makes it possible to support a plurality of types of lighting fixtures 100.

It has a structure that is

The fitting of the inspection unit 60 to the lighting device 30 is in a direction orthogonal to the operation direction of the inspection switch 62. The inspection unit 60 can be attached to and detached from the lighting device 30 without tools.

Since the inspection unit 60 has a configuration independent of the lighting device 30, the inspection unit 60 can be attached to a place other than the lighting device 30 depending on the shape of the appliance. At that time, the shape of the unit housing 61 may be changed as appropriate.
For example, in an instrument having a high overall height, it may be difficult to visually recognize the charging monitor 65 mounted on the inspection board 64 when it is attached to a recessed place.
In such a case, in the first embodiment, the inspection unit 60 may be fixed to the inner surface of the frame 29 of the light source unit 20 or the inner surface of the main body 10 close to the light source unit 20.
Further, as shown in FIG. 25, it is preferable to form the unit housing 61 of the inspection unit 60 in a box shape and fix the inspection unit 60 to the inner surface of the main body 10 close to the emergency light source 90. In FIG. 25, the unit housing 61 has a screw boss 69, and the unit housing 61 is screwed to the main body 10 from the lateral direction.
At that time, the unit housing 61 may be used as a design cover.

It coincides with the position of the screw hole 297 of the receiving portion 296.
Next, the screw 298 is inserted from the screw hole 297 of the conical screw receiving portion 296 and screwed into the screw hole 2792 of the screw mounting portion 279 of the light source mounting portion 27. The holding plate portion 2513 of the frame mounting bracket 25 is sandwiched between the front surface of the thick portion 2791 of the light source mounting portion 27 and the back surface of the frame 29. Since the inner diameter of the fitting hole 2514 is the same as the outer diameter of the root of the conical screw receiving portion 296, the frame mounting bracket 25 can be accurately positioned by tightening the screw 298.
In this way, the frame 29, the frame mounting bracket 25, and the light source mounting portion 27 are fixed by screws 298.
As described above, the frame mounting bracket 25 and the lens 21 are fixed by screwing the light source mounting portion 27 and the frame 29.

The lighting device is referred to as a board unit device 300, but the lighting device is a preferable specific example of the board unit device 300, the board unit device 300 does not have to be a lighting device, and the board unit device 300 does not have a lighting circuit. It doesn't matter if.

*** Explanation of the structure of the fixed structure of the connector ***
FIG. 28 is a diagram showing a mounting structure of the battery-side connector 3351 in the battery-side case 31 of the board unit device 300.
The battery-side case 31 is a lid-shaped device case 35 having one side open and a central portion recessed.
The battery-side case 31 has a connector mounting portion 551 for fixing the connector. Hereinafter, the battery-side connector 3351 is also simply referred to as a connector. The battery-side connector 3351 has a body convex portion 558 and a knob 559 on the body portion 560 of the hexahedron. The body convex portion 558 is a linear protrusion that protrudes horizontally from the side surface of the body portion 560 on the wall surface side toward the wall surface 556. The knob 559 is a pair of movable pieces attached diagonally upward from both sides of the tip of the body portion 560 in a wing shape.

The connector mounting portion 551 has a connector fixing hole 312.
The connector surface 3121 for fixing the connector of the connector mounting portion 551 and the wall surface 556 of the battery side case 31 are orthogonal to each other.
As shown in FIG. 30, the connector fixing hole 312 has a rectangular shape with a short side having a width W6 and a long side having a width W10, and has the same shape as the horizontal cross-sectional shape of the body portion 560. By providing the key-shaped overhanging portions 3122 at the four corners of the connector fixing hole 312, notches are formed on the long side of the connector fixing hole 312 through which the knob 559 passes. The connector fixing hole 312 has a thick cross shape as a whole.

The wall surface 556 has a plurality of guide ribs 552 for inserting the connector into the connector fixing holes 312. The guide rib 552 is a rail-shaped rib that projects vertically from the wall surface 556 toward the inside of the battery-side case 31.
As shown in FIG. 29, the guide rib 552 has a lateral restraining rib 535, a back restraining rib 554, and a lateral restraining rib 555.
As shown in FIG. 30, the distance W5 between the two lateral restraining ribs is the same as the opening width W6 on the short side of the connector fixing hole 312, and the same distance as the horizontal width of the side surface side of the body portion 560 of the connector or The intervals are almost the same.
The two lateral restraining ribs guide the position of the connector in the direction parallel to the wall surface 556 by inserting the body portion 560 of the connector between them.
The lateral restraining rib 553 is formed from the bottom surface 319 to the connector surface 3121.
The back restraint rib 554 and the lateral restraint rib 555 are not formed from the bottom surface 319 to the connector surface 3121, but are formed to about half the length from the bottom surface 319 to the connector surface 3121.
The lateral restraining rib 553 is continuously formed from one overhanging portion 3122 at the corner on the wall surface side to the bottom surface 319. That is, the surface of the lateral restraining rib 553 is formed continuously with the inner peripheral surface of the overhanging portion 3122 of the connector fixing hole 312.

The back restraint rib 554 is formed between the two lateral restraint ribs and is located in the center of the two lateral restraint ribs.
The height W7 of the back suppression rib 554 from the wall surface 556 is the same as the distance W8 between the connector fixing hole 312 and the wall surface 556. The height W7 of the back suppression rib 554 from the wall surface 556 is lower than the height W9 of the two lateral suppression ribs.
The back restraint rib 554 guides the position of the connector in the direction orthogonal to the wall surface 556. Further, if the height W9 of the lateral restraining rib is set to a height that contacts the side portion of the knob 559, the position of the connector in the direction orthogonal to the wall surface 556 can be guided.

As described above, the board unit device 300 shown in FIG. 28 includes a battery-side case 31 having a connector mounting portion 551 for fixing the connector of the battery harness 335. The battery-side case 31 has three guide ribs 552 in the vicinity of the connector mounting portion 551, and two outer guide ribs are arranged with a width substantially the same as the width of the connector. The rib between the two outer guide ribs is located in the center of the two guide ribs and is lower in height than the outer guide ribs.

Further, at least one of the two outer guide ribs is formed continuously with the connector fixing hole 312 of the connector mounting portion 551.

*** Explanation of the operation of the fixed structure of the connector ***
As shown in FIG. 29, when the battery-side connector 3351 is fixed to the battery-side case 31, the battery-side connector 3351 is inserted obliquely from the bottom surface 319 toward the connector mounting portion 551. Since the battery harness 335 can be bent in a substantially right angle direction, it is desirable to use an electric wire having bending resistance for the battery harness 335.
At the time of insertion, first, the lower end of the body portion 560 of the battery-side connector 3351 is brought into contact with the lateral restraining rib 553. At this point, the lower end of the body 560 of the battery-side connector 3351 is sandwiched between the two lateral restraint ribs.
After that, the body portion 560 of the battery-side connector 3351 is slid downward along the lateral restraint rib 553. As the battery side connector 3351 is slid, the body portion 560 of the battery side connector 3351 approaches the vertical direction from the slanted state. As a result, the body convex portion 558 of the body portion 560 of the battery side connector 3351 moves below the back suppression rib 554 and the lateral suppression rib 555, and the body portion 560 above the body convex portion 558 becomes the back suppression rib 554. Contact the lateral restraint rib 555. In this way, the body portion 560 of the battery-side connector 3351 is in the vertical direction. At this point, the upper portion of the body portion 560 of the battery-side connector 3351 becomes sandwiched between the two lateral restraining ribs, and cannot be completely moved in the left-right direction. At the same time, even if the body portion 560 is pressed against the wall surface 556, the battery-side connector 3351 cannot approach the wall surface 556 due to the back suppression rib 554.
On the side surface of the battery-side connector 3351 on the wall surface side, the body convex portion 558 projects toward the wall surface side, but the back suppression rib 554 and the lateral suppression rib 555 are up to about half the length from the bottom surface 319 to the connector surface 3121. It is formed. Therefore, the body convex portion 558 does not become an obstacle when the back restraining rib 554 and the lateral restraining rib 555 are further slid from the slanted state to the vertical direction. That is, even if the battery-side connector 3351 is in the vertical state, the body convex portion 558 is located below the back suppression rib 554 and the lateral suppression rib 555, so that the body convex portion 558 corresponds to the back suppression rib 554 and the lateral suppression rib 555. Never.
After that, the battery-side connector 3351 is slid downward while the body portion 560 is pressed against the wall surface 556, that is, the positions in the left-right direction and the back direction are suppressed by the three guide ribs 552.
Since the lower end of the lateral restraint rib 553 and the inner peripheral surface of the connector fixing hole 312 are continuous, the battery side connector 3351 is fitted into the connector fixing hole 312 so as to slide into the connector fixing hole 312 by moving the battery side connector 3351 downward. ..
The knob 559 passes through the notch of the connector fixing hole 312 in a state of being pressed against the body portion 560. On the other hand, the body convex portion 558 cannot pass through the connector fixing hole 312. That is, the battery-side connector 3351 is inserted into the connector fixing hole 312 up to the front of the body convex portion 558, and the knob 559 is restored so as to expand after passing through the connector fixing hole 312 to prevent it from coming off, and the battery-side connector 3351 is attached to the connector. It is fixed to the portion 551.

*** Explanation of the effect of the fixed structure of the connector ***
According to this embodiment, the battery-side connector 3351 can be easily fixed by providing the guide rib 552 that matches the shape of the connector mounting portion 551. The guide rib 552 is effective when the shape is such that it is difficult to provide the harness slit 313 on the bottom surface 319 of the battery side case 31.
Further, since there are two lateral restraining ribs matching the width of the side surface of the battery-side connector 3351, the battery-side connector 3351 can be aligned in the left-right direction. That is, the battery-side connector 3351 is sandwiched between the two lateral restraining ribs to regulate lateral movement.
Further, at least one lateral restraining rib 553 is continuously provided from the opening end surface of the connector mounting portion 551, and the battery-side connector 3351 can be easily guided to the opening of the connector fixing hole 312.
Further, since there is a back restraint rib 554 provided at one place along the center of the side surface of the body portion 560 of the connector, when the connector is pushed against the wall surface 556 of the battery side case 31 when the connector is inserted, the back direction of the connector is obtained. Movement is regulated.
Further, at least, the length of the back suppressing rib 554 is shortened so that the uneven portion of the connector such as the body convex portion 558 does not come into contact with the back suppressing rib 554. It is possible to prevent the connector from floating when the connector is inserted due to the unevenness of the side surface of the body portion 560.

*** Explanation of other configurations of the fixed structure of the connector ***
As shown in FIG. 31 (a), the lateral restraint rib 555 may be eliminated, and the lateral restraint rib 535 and the back restraint rib 554 may be connected to form a hook shape in the horizontal cross-sectional shape of the guide rib 552. This key shape is formed continuously with the key-shaped overhanging portion 3122 at one position of the connector fixing hole 312.
As shown in FIG. 31 (b), the back restraint rib 554 may be present in the entire space between the lateral restraint rib 555 and the lateral restraint rib 555, and the cross-sectional shape of the guide rib 552 in the horizontal direction may be concave. This concave shape is formed continuously with the two key-shaped overhanging portions 3122 of the connector fixing hole 312.
As shown in FIG. 31 (c), the lateral restraint rib 555 and the lateral restraint rib 555 may be formed from the wall surface 556 parallel to the long side of the body portion 560.
As shown in FIG. 31 (d), the lateral restraining rib 553 may be formed from the wall surface 556 parallel to the long side and the wall surface 556 parallel to the short side of the body portion 560.
Further, although not shown, all of the three guide ribs 552 or the two guide ribs 552 may be formed from the bottom surface 319 to the connector surface 3121 if there is no convex portion on the body portion on the wall surface side of the connector. In particular, if the three guide ribs 552 are continuously provided from the opening end surface of the connector mounting portion 551, the battery-side connector 3351 can be more easily guided to the opening of the connector fixing hole 312.
A harness slit 313 may be provided on the bottom surface 319 of the battery-side case 31, and a guide rib 552 may be provided on the wall surface 556.

*** Explanation of the configuration of the visual structure of internal parts ***
FIG. 32 is a diagram showing a visual structure of parts / materials inside the substrate unit device 300.
FIG. 33 is a three-view view of the battery-side case 31 and a three-view view of the substrate holder 333.
In this embodiment, an example in which the heat conductive member is a component to be confirmed from the outside will be described.

The direct mounting lighting fixture directly mounted on the ceiling has a limited height, and the heat radiating member cannot be mounted on the upper surface of the light source mounting portion 27. Therefore, the heat dissipation member 651 for direct attachment is sandwiched between the light source attachment portion 27 and the frame 29, and is attached so as to come into contact with the frame 29. By sandwiching the heat dissipation member 651 for direct mounting between the light source mounting portion 27 and the frame 29, the heat of the light source mounting portion 27 can be transferred to the frame 29, and the heat can be dissipated from the frame 29 to the outside air.

*** Explanation of the effect of using the heat dissipation member 651 for direct mounting ***

The light source mounting portion 27 mounts a protruding component 669 that protrudes toward the space, and the embedded heat radiating member 661 has a cut portion 670 that exposes the protruding component 669. The cut portion 670 is a U-shaped recess in which the outer peripheral end portion of the embedded heat radiating member 661 is recessed toward the inner peripheral side. Specific examples of the protruding component 669 are the frame mounting bracket 25 and the connector 243, and specific examples of the cut portion 670 are the spring passage recess 662 and the connector passage recess 663. A spring passage recess 662 is formed in the frame mounting bracket 25, and a connector passage recess 663 is formed in the connector 243.

*** Explanation of operation using the heat dissipation member 661 for embedding ***

As the embedded heat-dissipating member 661, a plurality of types of embedded heat-dissipating members 661 having the same outer shape or the same surface area but different thicknesses are prepared, and the height of the lighting fixture or the output of the light source is increased. The optimum embedded heat radiating member 661 may be attached from among a plurality of types of embedded heat radiating members 661 according to the height.

That is, the embedded heat radiating member 661 corresponds to the specifications of the lighting equipment in which the light source unit is used from among a plurality of types of disc-shaped heat radiating members having the same shape or area but different thicknesses of the embedded heat radiating member 661. It is a heat radiating member selected.

*** Explanation of the effect of using the heat dissipation member 661 for embedding ***
According to this embodiment, since the heat radiating portion is increased by the embedded heat radiating member 661, heat radiating can be effectively performed.
Further, since heat is radiated from the embedded heat radiating member 661 to the space, an effective heat radiating effect can be expected.
Since the screw hole 673 for fixing the socket 24 of the light source mounting portion 27 is used for fixing the embedded heat radiating member 661, there is no need to process the light source mounting portion 27 for fixing the embedded heat radiating member 661. Is.

However, both the direct mounting heat radiating member 651 and the embedded heat radiating member 661 may be used.
In order to improve the heat dissipation effect, the outer diameter of the heat dissipation member 651 for direct attachment is made the same as the inner diameter of the frame side plate 762 of the frame 29, and the heat dissipation member 651 for direct attachment is directly attached to the frame side plate 762 of the frame 29. You may dissipate heat.
In order to improve the heat dissipation effect, the outer diameter of the embedded heat dissipation member 661 may be larger than the outer diameter of the light source mounting portion 27. Further, the outer diameter of the embedded heat radiating member 661 may be smaller than the outer diameter of the light source mounting portion 27 due to the arrangement relationship with other parts.
In order to improve the heat radiating effect, heat radiating fins may be formed in the exposed portion of the direct mounting heat radiating member 651 and the embedded heat radiating member 661 to the internal space.

In the center of the frame surface plate 761, there is an opening for exposing the lens 21 and an inspection hole 294 for exposing the inspection switch 62.
The ceiling-side diameter D1 of the frame-side plate 762 is larger than the floor-side diameter D2 of the frame-side plate 762.
Since the diameter D1 on the ceiling side of the frame side plate 762 is larger than the diameter D3 of the side plate 12 of the main body 10, a gap space K4 is formed between the side plate 12 of the main body 10 and the inner surface of the frame 29, and the gap space K4 is formed. A spring fixing bracket 763 is provided. The width of the gap space K4 is the same as or substantially the same as the radial thickness of the spring fixing bracket 763.

A frame 29 is attached to the main body 10 by a mounting spring 751, and the main body 10, a lighting device 30, a battery unit 40, a power terminal block 50, and an inspection unit 60 are housed inside the frame 29.

The frame 29 has a spring receiver 752 for fitting the mounting spring 751 on the inner surface of the frame side plate 762.
The spring receiver 752 is a metal fitting, and has a pair of spring guides 753 on both sides, the spacing of which decreases as the diameter of the frame 29 decreases.

The luminaire 100 has an inspection switch 62 for checking the lighting of the light source of the light source unit 20.
The inspection switch 62 is attached to the inspection unit 60 attached to the main body 10. The inspection switch 62 has a pull rod. The tip of the pull rod passes through the inspection hole 294 and is exposed to the outside.

As shown in FIG. 44 (d), the mounting spring 751 is a wire rod, the diamond-shaped portion 754 on the tip side has a substantially diamond shape, and the root portion 765 faces outward from each other. The root portion 765 has a pair of straight portions 755 whose ends of the wire rod extend in the linear direction.
The mounting spring 751 has the same length as the height H of the lighting device 30. That is, in FIG. 43, the tip of the mounting spring 751 is at the same position as the upper surface 557 of the lighting device 30.
The widest spacing of the diamond-shaped wires of the mounting spring 751 is wider than the narrowest spacing of the spring receiver 752. The distance between the diamond-shaped wire rods of the mounting spring 751 at the widest distance is the same as the short side S of the lighting device 30 or a length equal to or less than the length of the short side S.

*** Explanation of the operation of the mounting structure of the main body 10 and the light source unit 20 ***
A method of mounting the mounting spring 751 and the spring receiver 752 will be described.
The spring fixing bracket 763 has two holes 764 through which the mounting spring 751 is passed, and after passing the straight portion 755 of the mounting spring 751 through the holes, insert the bracket so that the mounting spring 751 can rotate about the straight portion 755. By tightening, the mounting spring 751 is attached to the spring fixing bracket 763. At this time, the mounting springs 751 are in a state of being opened outward in the radial direction with each other.
Since the mounting spring 751 may be difficult to bend in the radial inward direction just by pushing it from below, a structure that is easy to bend by providing a sufficient clearance to bend in the radial inward direction when crimping the metal fitting at the straight portion 755 at the base. And.
The two spring fixing brackets 763 are fixed so as to face the outer periphery of the side plate 12.

The metal fitting of the spring receiver 752 is manufactured by bending the left and right sides of the trapezoidal sheet metal into a U shape.
Then, the two spring receivers 752 are fixed to the inner surface of the frame 29 by spot welding.

A method of fitting the mounting spring 751 and the spring receiver 752 at the construction site will be described.
First, the main body 10 to which the lighting device 30, the power terminal block 50, and the inspection unit 60 are attached is attached to the ceiling. Further, the battery unit 40 is incorporated into the main body 10.
Next, the frame 29 will be attached to the main body 10, but the frame 29 is supported from below by hand and provided in the main body 10 so that the position of the pull rod of the inspection switch 62 and the position of the inspection hole 294 match. The frame 29 is brought closer from the bottom to the top toward the mounting spring 751.
Since the central angle θ1 on the upper side of the spring receiver 752 is 35 degrees, if the tip of the mounting spring 751 is within the range of 35 degrees of the spring receiver 752, the tip of the mounting spring 751 is a pair of spring guides 753 of the spring receiver 752. It can pass between the spring guides 753 of the spring receiver 752.
Since the central angle θ2 between the line connecting the centers of the two spring receivers 752 and the line connecting the center of the inspection hole 294 and the central axis of the frame 29 is 45 degrees, the inspection hole 294 is connected from the straight line connecting the mounting springs 751. If the frame 29 is rotated about 45 degrees and brought closer to the frame 29 from the bottom to the top, the tip of the mounting spring 751 will surely fall within the range of 35 degrees, and it is necessary to repeat the up and down of the mounting frame 29 with the wrong angle in the rotation direction. Absent.
Theoretically, if the inspection hole 294 is in the range of 45 degrees + 35 degrees / 2 to 45 degrees-35 degrees / 2 from the straight line connecting the tips of the mounting spring 751, the tip of the mounting spring 751 is within the range of 35 degrees. Will enter.

Before the frame is mounted, the mounting springs 751 are open to each other in the radial direction outward. Therefore, when the frame is mounted, the mounting springs 751 are tilted inward in the radial direction along the inner surface of the frame 29. Slide the tip between the spring guides 753 of the spring receiver 752.
That is, before mounting the frame, the mounting spring 751 is wider than the outer diameter of the frame 29, and when the frame 29 is mounted, the spring gradually closes along the inner surface of the frame 29, and is finally pushed up to form the mounting spring 751. It fits with the spring receiver 752. When the mounting spring 751 and the spring receiver 752 are fitted, the positions of the inspection switch 62 and the hole inspection hole 294 are completely matched, and the inspection switch 62 is exposed from the inspection hole 294.
In this way, by attaching the frame 29 to the main body 10 so that the inspection switch 62 is exposed from the inspection hole 294, the attachment spring 751 is fitted into the spring receiver 752.
The pull rod of the inspection switch 62 and the inspection hole 294 of the frame 29 serve as a guide for positioning at the time of insertion, and at the same time, when the main body 10 is housed inside the frame 29, the light source 26 and the inspection switch 62 are pulled with respect to the frame 29. The stick and the stick are automatically in place.

As shown in FIG. 44, the spring receiver 752 has a structure in which the distance between the inlets of the spring guide 753 is wider than the distance between the outlets and the distance between the outlets of the spring guide 753 is narrower than the maximum width of the mounting spring 751. There is. This structure is such that the mounting spring 751 and the spring receiver 752 can be easily inserted.
When the main body 10 is housed inside the frame 29, the tip of the mounting spring 751 is inserted between the spring guides 753 by pushing up the frame 29 so that the pull rod is inserted into the inspection hole 294. After that, as the frame 29 is pushed up and the mounting spring 751 fits into the spring receiver 752, the main body 10 and the frame 29 are positioned in the rotational direction.
When the frame 29 is pushed in and the maximum width portion of the mounting spring 751 gets over the outlet portion of the spring receiver 752, the restoring force of the mounting spring 751 is switched to the force of pulling the main body 10 with respect to the spring receiver 752, and this force is switched to the main body. It is the holding force of the frame 29 with respect to 10.

Next, the arrangement positions of the mounting spring 751 and the spring receiver 752 will be described.
The lighting device 30 is laid out in the center of the main body 10. When the light source unit 20 is mounted on the ceiling, it is necessary to slide the frame 29 upward, but it is necessary to secure a work space for sliding the light source unit 20. Since the mounting springs 751 are arranged symmetrically at two locations, they are mounted between the outer peripheral surface 354 of the lighting device 30 which is an internal component facing the inner surface of the frame 29 of the lighting device 30 and the inner surface of the frame side plate 762 of the frame 29. An arrangement space K5 into which the spring 751 is inserted is provided. The arrangement space K5 is a space formed by forming the frame 29 into a truncated cone shape. Since the gap space K4 is formed between the side plate 12 and the frame side plate 762, the maximum width of the arrangement space K5 in the radial direction is the same as the gap width of the gap space K4. When the outer peripheral surface 354 of the lighting device 30 is the same as the outer peripheral surface of the side plate 12 of the main body 10, the width of the arrangement space K5 in the radial direction becomes smaller toward the frame surface plate 761. The cross-sectional shape of the arrangement space K5 in the radial direction including the central axis of the frame 29 is a right triangle.

The lighting device 30 has a rectangular parallelepiped shape, and the lighting device 30 is arranged so as to have a long side L and a short side S across the center of the main body 10, and includes a mounting spring 751 and a spring receiver 752. Is fitted between the outer peripheral surface 354 on the short side S of the lighting device 30 and the inner peripheral surface of the frame side plate 762 of the frame 29.
Since the mounting spring 751 is inserted into the space between the outer peripheral surface 354 on the short side S of the lighting device 30 and the inner peripheral surface of the main body 10, the mounting spring 751 is likely to fall excessively inward in the radial direction. Even if this happens, there is no risk that the mounting spring 751 will fall inward due to the presence of the outer peripheral surface 354 of the lighting device 30.

*** Explanation of the effect of the mounting structure of the main body 10 and the light source unit 20 ***
According to this embodiment, since the mounting spring 751 is attached to the main body 10 instead of the frame 29, in the case of a direct mounting lighting fixture, the mounting spring 751 is not hidden by the design surface of the frame 29, and the mounting spring is not hidden at the time of mounting. Since the position of 751 can be visually recognized, it is easy to fit the mounting spring 751.

Since the frame 29 has a tapered shape or a truncated cone shape, a gap space K4 is formed between the frame 29 and the side plate 12, and the spring fixing bracket 763 can be arranged between the side plate 12 and the frame side plate 762.

Since the frame 29 has a tapered shape or a truncated cone shape, an arrangement space K5 can be formed between the outer peripheral surface 354 of the lighting device 30 and the inner peripheral surface of the frame 29, and the mounting spring 751 and the spring receiver 752 can be formed. Can be arranged in the arrangement space K5 between the outer peripheral surface 354 of the lighting device 30 and the inner peripheral surface of the frame 29.

Since the mounting spring 751 is arranged between the outer peripheral surface 354 of the lighting device 30 and the inner peripheral surface of the frame 29, the length from the tip of the mounting spring 751 to the root portion 765 is set to the outer circumference of the lighting device 30. It can be freely designed within the range of the height H or less of the surface 354. The width of the mounting spring 751 can be freely designed within the range of the length of the short side S of the lighting device 30 or less or the length of the arcuate surface of the outer peripheral surface 354 of the lighting device 30 or less.

Further, since all the parts fixed to the main body 10 are housed inside the cylindrical body having the diameter D3 of the main body 10, the inside of the arrangement space K5 formed on the inner circumference of the frame side plate 762 of the frame 29 of the truncated cone. If so, the mounting spring 751 may be made longer than the height of the lighting device 30. That is, the length from the tip of the mounting spring 751 to the base can be set to the same length as the height of the frame 29 at the maximum.

Further, the metal fitting of the spring receiver 752 is formed by bending both sides of the sheet metal, so that it is easy to process and the manufacturing cost can be suppressed.
Further, by aligning the pull rod of the inspection switch 62 with the inspection hole 294 of the frame 29 and then inserting the frame 29, the frame 29 can be mounted in the regular position in the regular orientation.
Further, the main body 10 and the frame 29 can be mounted in a space-saving space, and the size of the appliance can be reduced.

In addition, the mounting structure of this embodiment can be used for a plurality of types of direct mounting lighting fixtures, parts can be shared with other models, parts can be standardized, and a plurality of parts can be used without adding new parts. It is possible to suppress an increase in the number of unnecessary parts when manufacturing a model.

*** Explanation of other configurations of the mounting structure of the main body 10 and the light source unit 20 ***
By adjusting the angle of the substantially rhombus shape of the mounting spring 751, the force required for mounting the frame 29 and the force required for removing the frame 29 can be adjusted. For example, when the mounting spring 751 is adjusted to an angle such as the rhombus portion 754 in FIG. 44 (d) to the arrowhead portion 756 in (e), the holding force becomes larger than the force at the time of mounting.
The inspection hole 294 may be provided on the line connecting the centers of the spring receiver 752. If the central angle θ2 of the line connecting the center of the spring receiver 752 and the line connecting the inspection hole 294 and the central axis is set to 0 degrees, the inspection hole 294 can be fitted so as to match the straight line connecting the mounting spring 751. The frame 29 can be easily fitted.
If the length of the mounting spring 751 is set to half or less of the height of the frame 29, the size of the appliance can be reduced.
The inspection switch 62 is not a pull rod type switch, but may be a push button type switch exposed from the inspection hole 294.
The frame side plate 762 of the frame 29 may be a cylindrical body having an outer diameter of D1. The frame side plate 762 of the frame 29 may be a polygonal prism cylinder having a polygonal cross section.
